Zigzag
Half-square triangles (complete first)
Two-at-a-Time Half-Square Triangles
HST Unit
Produces two matching Half-Square Triangles (HSTs) from a pair of squares.
- Cut one square from each fabric using the 2-at-a-time starting size.
- Place the two squares right sides together and mark one diagonal line.
- Sew 1/4 inch from both sides of the marked line.
- Cut on the marked line to separate the two units.
- Press open and trim each HST to unfinished size.
Pro tip: When the pattern needs an odd HST count, this method is ideal for making the final pair without committing to larger batches.
Subunits first
This mosaic layout uses only half-square triangle units, each the same grid size. See the HST technique above. Make these counts: 16 HST Units.
